I have a Sonnet Temp Pro in RAID 0 w/OS X 10.9.4 - my main production environment

I had a little free time and installed OS X 10.10 onto a spare 64GB SSD on the back plane

rebooting with Startup Disk or by holding Option on the keyboard and selecting the 10.9.4 installation results in loop of the OS X 10.10 installer starting (from here I have to select the 10.10 as startup disk)

- any ideas to get the 10.9.4 back?
